<p class="level0">Pass a long that holds a bitmask of CURLPROTO_* defines. If used, this bitmask limits what protocols libcurl may use in a transfer that it follows to in a redirect when <a Class="emphasis" href="./CURLOPT_FOLLOWLOCATION.html">CURLOPT_FOLLOWLOCATION</a> is enabled. This allows you to limit specific transfers to only be allowed to use a subset of protocols in redirections. By default libcurl will allow all protocols except for FILE and SCP.
